一、发展喷灌是节约水源、增加农作物产量的有效途径喷灌的优点很多,主要是省水、省工、有利于增产。新疆河流来水量每年约960亿立方米,总引水量每年约400亿立方米。要灌溉4000万亩农田及园林,实际上不能满足作物播种和生长的需要。若再考虑牧业生产发展的需要,按每头畜1亩饲草饲料 First, the development of sprinkler irrigation is an effective way to save water and increase crop yield Sprinkler irrigation has many advantages, mainly water, labor, is conducive to increasing production. The amount of water in Xinjiang’s rivers reaches about 96 billion cubic meters a year, with a total annual water discharge of 40 billion cubic meters. To irrigate 40 million mu of farmland and gardens can not actually meet the needs of planting and growing crops. If we consider the needs of animal husbandry and production development, livestock per acre forage grass
